China on Tuesday urged Israel to "stop attacking Rafah", after the Israeli army said it took "operational control" of the Palestinian side of the Rafah border crossing between Gaza and Egypt.

"China... strongly calls on Israel to heed the overwhelming demands of the international community, stop attacking Rafah, and do everything it can to avoid a more serious humanitarian disaster in the Gaza Strip," Chinese foreign ministry spokesman Lin Jian said.

Israel carried out strikes on the Gazan city of Rafah overnight as it sought to put "pressure" on Hamas ahead of talks in Egypt on Tuesday aimed at sealing a truce proposal endorsed by the group.

After having vowed for weeks to push into the southern border town, Israel called on Monday for Palestinians in eastern Rafah to leave for an "expanded humanitarian area" ahead of a ground incursion.

An AFP correspondent in the city reported heavy bombardment throughout the night, while the Kuwaiti hospital there said on Tuesday in an updated toll that 11 people had been killed and dozens of others injured in Israeli strikes.

Israel's army then said on Tuesday ground troops were carrying out an operation in eastern Rafah.

Beijing on Tuesday said China "expresses grave concern over Israel's planned launch of a ground military operation against Rafah".

"War and violence cannot fundamentally solve the problem and cannot bring about true security," Lin said.
